CHAMBER-VESSEL.

SPECIFICATION forming part of Letters Patent No. 372,063, dated October25, 1887.

Application filed February 19, 1887. Serial No- -2S,l5l. (No model.)

to make and use the same, reference being bad to the accompanyingdrawings, and to the let ters and figures of reference marked thereon,whichform a part of this specification.

My invention relates to an improvement in chamber-vessels; and itconsists in certain improvements in that part called the diaphragm, aswill be hereinafter fully set forth and described in the specification,and more particularly pointed out in the claims.

My invention relates to that class of chamber-vessels in which aurinal-diaphragm is inserted into and made a part of said chambervesselfor rendering the latter'noiseless, it being adapted for the use ofbothsexes.

Figure 1 is a top view of a chamber-vessel having myimproveddiaphragmtherein. Fig. 2 is avertical section of the same with the diaphragmshown entire.

A represents the chamber-vessel, and B the diaphragm, which latter isattached by one edge' throughout its entire length to the inner wall ofthe vessel A. It tapers in width from the part which forms its upper orreceiving end to its lower or discharge end, which latter narrows almostto a point. The upperend is .formed into a shallow dish-like part and extends from one side to about thecenter of the vessel A. At this point'itcurves reversely toward the attached side, and then again forward anddownward. Its general form is that of a fiat spiral, decreasingin widthfrom its upper to its lower end, and bent edgewise to fit the inner wallof the chamber-vessel, to which it'is securely attached. Its larger partat the receiving end occupies about one-fourth the cavity of the vessel,or a little more than that. Its length, width, and pitch may be varied.It is somewhat concave or dished on the upper surface and its free edgeis made highest, so as to cause the stream issued upon it to bedeflected toward the wall on the side to which it is attached. Thisattachment extends from end to end. The discharge end is a little abovethe bottom of the vessel. A slight filletis put in next the wall of thevessel to strengthen the attachment and take out the angle by fillingit.

In the process of manufacture the diaphragm is molded, and whensufficiently dry to sustain its form is inserted into the chamber-vesselafter the latter has been made, and before entirely dry. Care is takento wet the surface where it is to be attached and to have the edge(which latter should be thicker than the body part) well covered withthin wet clay, so as to insure its complete attachment. It is thenfilleted along the edge next the wall of the vessel and the filletconcaved, when it is ready for the kiln.

The handle 0 may be placed on that side of the chamber-vessel mostconvenient for pouring out the contents.

I claim as my invention-- 1. In a chamber vessel, a diaphragm of spiralform attached to the inner wall by one edge, extending inwardlytherefrom, and depressed next said attached edge to form a conduit closeto said inner wall, substantially as and for the purpose set forth.

2. In a chamber-vessel, the inclined volute or spiral plate diaphragmattached by one edge throughout its length, having a broad receivingupper end, and tapering from the latter to the discharge end,substantially as hereinbefore set forth.

3. Inachamber-vessel, the improved spiralshaped diaphragm 13*, having aheavy rounded bead, on its top end, the latter extending from one sideto about the middle of said chambervessel and curved toward the wall ofthe latter, thereby lessening its width from thence to its dischargeend, said diaphragm being highest on its free edge to direct the streamof urine around near the wall of said vessel, substantially as and forthe purpose hereinbefore set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN A. DAVIS.
